    摘要： A gas spring assembly includes an end member, a piston assembly and a flexible sleeve secured therebetween. An end closure secures an end of the flexible sleeve to the piston assembly. A connector fitting connects the end closure to a support post of the piston assembly. The connector fitting includes a fitting passage and a first annular groove. A jounce bumper assembly is supported on the connector fitting. The jounce bumper assembly includes a bumper body and a bumper mount. The bumper mount includes securement pin having a second annular groove. A retaining member is received within the first and second annular grooves such that the jounce bumper assembly can freely rotate relative to the connector fitting while substantially restricting axial displacement of the jounce bumper assembly relative to the piston assembly during such rotation.

    摘要： A vehicle suspension system includes a pair of suspension assemblies mounted on a pair of spaced vehicle frame members for supporting a vehicle body on the vehicle wheels. A torsion axle extends between the pair of suspension assemblies and terminates in a pair of stub shafts. The axle is mounted on a pair of spaced frame brackets attached to the vehicle frame. An air spring extends between the vehicle frame and an outer end of a support arm pivotally mounted on each end of the torsion axle. The stub shafts are supported within an outer tube of the torsion axle by a plurality of elastomeric members. One end of each stub shaft is connected to a spindle arm which has a spindle extending from an opposite end of the arm. The length of the air spring support arm and the distances between the pivot axis of the support arm and the axii of the spindle and torsion axle are chosen so that the surface of the air spring is always out of contact with the mounting bracket and has a portion inboard between the axis of the spindle and axis of the torsion axle.

    摘要： A self-steering auxiliary axle assembly having an elastic member for use as a steering damper is provided. The axle assembly has a frame with an axle supported by the frame in spaced relation therefrom with retracted and highway positions. At least one air spring is arranged between the axle and the frame. The air spring is actuateable between an operative mode for damping the axle in the highway position and a non-operative mode when in the retracted position. The axle has opposing ends with spindle assemblies pivotally supported thereon for permitting rotation of said spindle assemblies relative to said axle. Steering arms extend from the spindle assemblies. A control rod interconnects the steering arms for linking the spindle assemblies together. The elastic member interconnects one of the steering arms and the axle for damping the rotation of the spindle assemblies relative to the axle. The steering damper has opposing connections movable relative to one another with the opposing connections joined by the elastic member.

    摘要： An air spring has a pair of spaced end members for mounting the spring at spaced locations on a structure. A flexible sleeve of elastomeric material is sealingly engaged with the end members and forms a pressurized fluid chamber therebetween. A post is mounted on one of the end members and extends into the fluid chamber. A shock absorbing two-piece bumper includes a rigid base which is formed with an axial opening and is seated upon one of the end members with the post extending into the opening. An elastomeric member is mounted within the axial opening of the rigid base member and is snap-fitted onto the post. The upper end of the elastomeric member extends outwardly over the upper end of the base to engage the opposite end member upon the air spring failing or experiencing a large deflection. The two-piece bumper provides a high load carrying capability with low deflection and replaces the heretofore used single member elastomeric bumper.
